Renault chief Luca de Meo warned Saturday that European carmakers could face fines of 15 billion euros if they fail to respect EU emissions rules, calling for "some flexibility" as electric car sales slow on the continent.
He told France Inter radio: "In order to meet CO2 emission standards calculated on average for all cars sold, manufacturers will have to reduce their production by more than 2.5 million vehicles to avoid being penalized."
De Meo, who is also president of the European Automobile Manufacturers Association (ACEA), said an EV car can compensate for four thermal cars.
"We are now preparing for 2025 because we are taking orders for the cars we're going to deliver. According to our calculations, if EV production remains at today's level, the European industry may have to pay 15 billion euros in fines or give up production of more than 2.5 million units," he said.
"We need to be given a little flexibility. Setting deadlines and fines without being able to make that more flexible is very, very dangerous," he warned.
In August, battery-electric cars accounted for 12.5% of the EU car market, with a 10.8% drop in sales year-on-year.
The Renault chief underlined the importance of the EV market for European industrial battery manufacturing projects. "If electric cars do not sell, these projects will face difficulties," he added.
To explain the weak market for electric vehicles, de Meo cited the high prices of cars, the very slow installation of charging stations and "uncertainty" about the subsidies for the purchase of electric vehicles.
He said the German government ended its electric car subsidy program last December, leading to a drastic drop in sales.
Commenting on those subsidies, he stressed "we need stability, visibility" and "a certain consistency" in our policies.
The European automobile industry is under intense pressure from Chinese competition. Volkswagen warned this week that it would consider closing factories in Germany for the first time in its 87-year history.
This should not happen to Renault, which has already made savings, de Meo assured. "A few years ago, we had to make a very hard decision by reducing production capacity by more than one million vehicles," he explained.
